Quote from the NewsGuard article: “As chatbots adopted real-time web searches, they moved away from declining to answer questions. Their non-response rates fell from 31 percent in August 2024 to 0 percent in August 2025. But at 35 percent, their likelihood of repeating false information almost doubled. Instead of citing data cutoffs or refusing to weigh in on sensitive topics, the LLMs now pull from a polluted online information ecosystem — sometimes deliberately seeded by vast networks of malign actors, including Russian disinformation operations — and treat unreliable sources as credible.”
